Hypermethylation of lncRNA MEG3 impairs chemosensitivity of breast cancer cells

Decreased expression of lncRNA MEG3 in breast cancer is associated with poor prognosis

Background: Dysregulated long non-coding RNAs (lncRNAs) play critical roles in tumorigenesis and tumor progression. The purpose of this study was to investigate the relationship between lncRNA MEG3 expression and breast cancer (BC) clinicopathological characteristics and prognosis. Methods: Expression levels of lncRNA MEG3 in 257 BC specimens were determined by quantitative real-time PCR (qRT-P...

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Chemosensitivity in Breast Cancer

Gambogenic acid alters chemosensitivity of breast cancer cells to Adriamycin

BACKGROUND Breast cancer remains a major health problem worldwide, and is becoming increasingly resistant to traditional drug treatments. For instance, Adriamycin (ADR) is beneficial for the treatment of breast cancer. However, its wide application often leads to drug resistance in clinic practice, which results in treatment failure. Gambogenic acid (GNA), a polyprenylated xanthone isolated fro...

Roles of lncRNA in breast cancer.

Recent systematic genomic studies have revealed a broad spectrum of lncRNAs that are involved in a variety of disease (diseases), including tumor progression, by regulating gene expression at epigenetic, transcriptional and post-transcriptional levels. However, their exact roles of physiological function and the mechanism (mechanisms) of action are yet to be clarified. In breast cancer research...
